Abstract
The utility model belongs to technical field of security protection device for hoisting machinery, in particular to a lifting height limiter. The utility model applies in that when a steel rope on the fixing position of a wound roll approaches a switch and less than switch motion operating distance to make the switch operate the output control wound roll to limit the lifting altitude; the utility model is characterized in that an approach switch is provided at the outer flank of the wound roll and at the position at the same height with the wound roll axes; a controller is provided at the lower part of the approach switch; the approach switch and the controller are fixed on the floor via a bracket; the relative position between the approach switch and the wound roll and the position of bracket fixed on the floor are convertible. The utility model has the advantages of reliable control, simple mode, long service life, low cost, convenient installation and debugging; and needs no workload after debugging. The utility model can be applicable in various industries in the utmost limit protection operation of ore bridges, the stacker cranes, various overhead travelling cranes with hoists and windlasses.
Description
Technical field
The utility model belongs to elevator machinery class safety guard technical field, particularly a kind of steel cable induction type lifting altitude killer.
Background technology
At present, lifting altitude killer commonly used has weight hammer type, steel cable guide rail displacement-type, driving type and coding type etc. several in elevator machinery class safety guard.Weight hammer type lifting altitude killer has adopted suspension hook to collide the principle that lever makes the switch motion of counterweight balance formula when the rising limit, has shortcomings such as fragile, poor reliability, maintenance be big.Steel cable guide rail displacement-type lifting altitude killer has adopted steel cable to arrange moving guide rail on reel, and the principle of connecting rod pull switch action when suspension hook is positioned at the rising limit often exists and shortcoming such as damages, service life is short, maintenance is very big.The reductor of driving type lifting altitude killer is connected with drum shaft, selects transmitting ratio to make worm gear wheel shaft upper-part make switch motion when the control position, exist complicated, debugging inconvenience is installed, maintenance is big and the more high shortcoming of cost.The coder of coding type lifting altitude killer and drum shaft connection, the output pulse code is accurately represented reel revolution and angle, has poor reliability, big, the more high shortcoming of cost of maintenance equally.
Summary of the invention
The utility model proposes a kind of steel cable induction type lifting altitude killer, used on reel, have steel cable that fixing rule arranges with near the spacing of switch less than switch motion apart from the time, make switch motion, its output control reel, thereby limited lifting altitude.
Hoisting crane is under equipment of determining and environmental conditions, and steel cable has on reel when fixedly rule is arranged, and certain a bit represents the suspension hook certain height in a certain position on reel on the steel cable.When being positioned at the rising limit as suspension hook, utilize steel cable on reel the last circle certain a bit with electromagnetic induction near switching space less than the switch motion distance, then the principle of switch motion makes controller output signal make reel stop operating, suspension hook stops to rise.
The utility model comprises reel, steel cable, bearing, drum shaft, bearing seat, the floor, suspension hook, be wound with the bottom on the reel steel cable of suspension hook is arranged, drum shaft is equipped with in the reel both sides, insert in the bearing that is contained on the bearing seat respectively, bearing seat is fixed on the floor, it is characterized in that: be equipped with near switch at reel outside certain distance and spool axis height same position, connect controller near the switch bottom, be fixed on the floor by support near switch and controller, being fixed on adjustable positions on the floor near switch and reel relative position and support, is 25～80mm near switch with steel cable distance on reel.
Concrete control principle is as follows: hoisting crane, is failure to actuate near switch with between near switch during no steel cable when reel in real-world operation, and the reel of hoisting crane scrolling steel cable under the driving of motor makes normal rising of suspension hook or decline.When at reel and between near switch steel cable being arranged, move immediately near switch, its output switching signal is delivered to controller, and the control hoisting crane cuts off the reel power supply, and reel is stopped operating, and reaches that restriction hoists or the purpose of falling head.Hoisting crane is in different lifting constructions; need diverse locations such as control protection suspension hook rising limit position, falling-threshold position, rising early warning position, decline early warning position, certain height position; can adjust respectively near switch and reel relative installation; make suspension hook when corresponding height cooresponding on the reel steel cable be equal to or slightly less than operating distance near the switch distance, can accomplish multifunction protection to hoisting crane.
The utility model control is reliable, mode is simple, long service life, with low cost, Installation and Debugging convenient, debugging back service-free work capacity, can be widely used in the limit protection operation of every profession and trade door, crane in bridge type, tower crane, various electric hoist crane and winch etc.
Description of drawings

Fig. 2 is a left view of the present utility model.
The specific embodiment
As Fig. 1, steel cable induction type lifting altitude killer shown in Figure 2, comprise reel 1, steel cable 2, bearing 3, drum shaft 4, bearing seat 5, floor 6, suspension hook 7, be wound with the bottom on the reel 1 steel cable 2 of suspension hook 7 is arranged, drum shaft 4 is equipped with in reel 1 both sides, insert in the bearing 3 that is contained on the bearing seat 5 respectively, 3 on bearing is fixed on the floor 6, it is characterized in that: be equipped with near switch 10 at reel 1 outside certain distance and reel 1 axis height same position, connect controller 9 near switch 10 bottoms, be fixed on the floor 6 by support 8 near switch 10 and controller 9, being fixed on adjustable positions on the floor 6 near switch 10 and reel 1 relative position and support 8, is 25～80mm near switch 10 with steel cable 2 distances on reel 1.
From on January 10th, 2006, at elevator machinery factory of Anshan iron and steel plant mechanical development main office steel cable induction type lifting altitude killer on probation, near the switch model be: IB03-AG2, the controller model is: RXL2A12B1P7, drum diameter is 300mm, cable diameter is 15mm, is 25mm near switch and reel steel cable operating distance, and lifting altitude is 6 meters.Used 4 months, trouble free, no misoperation, non-maintaining.
Limited height: the suspension hook upper end is 500mm with reel lower edge distance, requires error to be ± 20mm.
Debugging recording following (order 1 to 5 be unloaded, 6 for handling 1 to 4 ton weight do not wait to 10) is surveyed unit: mm.
